    NullPointerException thrown on cmp bean deployment

    Richard Barrington Newbie

      Hi.

      I've got a very simple bean made with MyEclipse, which is just a primary key and associated XDoclet generated objects. Nothing tricky going on at all. Deploying the bean results in a NullPointerException being thrown. Unfortunately there is no useful information aside from the line numbers reported, so I'm flying blind without a good knowledge of the JBoss source code. I'll hazard a guess and say it's probably a deployment descriptor error, but I could be wrong there - but if it was, wouldn't a deployment exception be thrown instead?

      Any suggestions would be appreciated.

      The error is posted below:
